Abstract
Abstract An electric noise absorber for holding a conduit of an electronic device comprises a retaining case composed of two box-shaped cases and auxiliary cases. A sponge-like member is fitted into the auxiliary case to prevent longitudinal movement of the cord or cable. A box-shaped case contains a magnet having a recess for receiving the cord or cable. It is possible to easily and securely attach and detach the electric noise absorber to the cord or cable by simply opening and closing the cases.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
115 words
An electric noise absorber comprising: a magnetic body abutably divided into two parts, each of said two parts having an abutment surface which has a recess and said magnetic body configured to enclose a portion of an electric conductor; a retaining case including a pair of cases hingedly connected with each other for holding said magnetic body; an auxiliary case connected to and adjacent a side of said retaining case, said auxiliary case including at least one cavity; and an elastic press member sized, shaped, and positioned to fit into a cavity of said auxiliary case and to engage and hold a conductor when said retaining case is in a closed condition about the conductor.
Claim 2
Dependent Claim
115 words
An electric noise absorber comprising: a magnetic body abutably divided into two parts, each of said two parts having an abutment surface which has a recess and said magnetic body configured to enclose a portion of an electric conductor; a retaining case including a pair of cases hingedly connected with each other for holding said magnetic body; an auxiliary case connected to and adjacent a side of said retaining case, said auxiliary case including at least one cavity; and an elastic press member sized, shaped, and positioned to fit into a cavity of said auxiliary case and to engage and hold a conductor when said retaining case is in a closed condition about the conductor.
Claim 3
Dependent Claim
28 words
